24. There are several ways to subtract the background in the experimental data and each method have some uncertainty. In our case we chose to approximate the background as a straight line.
25. The fitting parameters to the experimental data are a = 0, b = 7.87, and c = 0.094. The theoretical fitting parameters are a = 0.35, b = 5.53, and c = 0.94.
26. The new fit for the theoretical relation of area ratio against oxygen concentration, which considers the experimental limit of oxygen concentration resulted in the following fitting parameters: a = 0.23, b = 5.80, and c = 0.998.
